Slick City reaches 50 parks with Milford opening

Slick City Action Park has opened its 50th park in Milford, Massachusetts, marking a fast-growth milestone for the indoor dry-slide attraction business.

The Milford venue arrives four years after the company's first park opened in Lakewood, Colorado. Slick City says it opened 25 locations during 2026 alone, underscoring how quickly the concept has moved from a new entertainment format into a broader network of corporate, affiliate and franchise locations.

The brand was founded in 2021 and began franchising in early 2024. By September, it reported 173 locations signed or open globally and more than six million guest visits since launch. More than 45 per cent of those visits came in the preceding 12 months, according to the company.

Milford is significant because it gives the network a visible Massachusetts foothold while also serving as the numerical 50th-park marker. The company says two further European locations are being prepared, giving its development programme both domestic and international dimensions.

Co-founder and chief executive Bron Launsby credited the growth to franchise owners and park teams, alongside guest demand for the category. That mix matters in a franchise model: rapid site growth can create opportunity, but it also increases the importance of training, consistency and local operations.

For operators considering family-entertainment concepts, Slick City's trajectory illustrates a different expansion playbook from food or service franchising. The product is a purpose-built indoor activity venue, with proprietary dry-slide technology at its centre, so scale depends on real estate, construction and operating execution as much as consumer marketing.

The Milford opening does not by itself determine the brand's long-term economics. It does, however, give the company a clear milestone to point to as it adds locations across the United States and Europe — and makes the next phase of franchise support and site selection more consequential.
